Ampere-hour

A unit of electric charge: one ampere flowing for one hour, or 3600 coulombs. Battery capacity is rated in ampere-hours, which measure charge, not energy.

Coulomb

The SI unit of electric charge; one ampere flowing for one second. Battery engineers prefer the ampere-hour, which is 3600 coulombs, because cells deliver their charge over hours.

Faraday’s law of electrolysis

The amount of substance transformed at an electrode is proportional to the charge passed: one mole of electrons per Faraday. It converts a material’s formula into its theoretical capacity in mAh/g.

Theoretical capacity

The capacity a material would deliver if every available lithium ion took part, computed from Faraday’s law and the molar mass. Practical capacity is lower because not all the lithium can be removed reversibly.
